SegFault while edditing commit message on Magit

[julienJean99]

Expected behaviour: not crash emacs

The behaviour observed:
when opening the commit message buffer if I stay too long (less then a minute) it crashes emacs

Reproduce the issue.: it started happening after I installed CCLS and start to edit commit message

M-x magit-version RET
Magit 20180720.1712, Git 2.13.6, Emacs 25.3.1, gnu/linux

I doubt that it would be of any use but here is the stack trace:

I'm also posting the issue on the Magit GitHub

This looks like an upstream issue.
